Agilent Technologies G1311B 1260 Quaternary Pump

Product Information

Introducing the Agilent Technologies G1311B 1260 Quaternary Pump, a robust and versatile pump that boasts a pressure of up to 600 bar, allowing for the use of small particle columns to achieve higher resolutions and faster separations. This quaternary pump enables a wide flow range of up to 10 mL/min, making it the perfect choice for 4.6 and 3.0 mm id columns. One of the standout features of this pump is its easy, fast, and secure transfer of methods from HPLC to sub-2-micron columns. Noteworthy is the integration of new degasser technology within the pump, ensuring efficient performance. This beautifully designed piece of equipment has a Class 1 condition, making it an exceptional find in the used equipment market. Used primarily for HPLC, this pump is particularly well-suited for applications involving analytical chemistry, biochemistry, and pharmaceutical analysis. Aside from its conventional uses in laboratories, the Agilent G1311B series also finds applications in environmental analysis and food and beverage industries.
